.NEAR TERM...
(Rest of tonight)
Issued at 919 PM CDT Wed Apr 24 2024

A cold front that moved in a north to south manner across the
area earlier today, now extended about from the eastern VA/NC,
westward across north/central AL, to southern AR. The front that
was on a weakening trend as it moved across the area, thus little
to no shower activity was realized today.

Surface high pressure over the Great Lakes was ridging to the
south and controlling our sensible weather. Except for few to
scattered passing high altitude clouds, no weather of consequence
was occurring, nor is expected for the remainder of the overnight.
With the airmass change, overnight low temperatures should trend
a bit cooler than last night, bottoming out in the mid 40s to near
50 degrees. A light northerly flow of around 5 mph should continue
as well. Except for a few tweaks on sky cover and temperatures, no
big changes were needed at this time.

.SHORT TERM...
(Thursday through Saturday)
Issued at 207 PM CDT Wed Apr 24 2024

Tomorrow, a severe synoptic system in the Plains will begin to
influence our weather closer to home. A upper level trough and
associated surface low pressure system will move into the Plains
and support severe weather for the central CONUS. Closer to home,
the trough will aid in lifting the boundary passage from today
back north through the area. This will increase cloud cover
gradually throughout the day and support low to medium rain
chances starting Thursday night and lingering into Friday morning.
After this brief period of low rain chances, the forecast for the
remainder of the weekend remains dry yet impacts from the system
in the Plains will continue through the weekend.

The low pressure system will slowly trek east through the short
term and place us sandwiched between low pressure to our west and
high pressure to our north and southeast. This will result in a
constriction in the pressure gradient yielding a few days of
gusty winds. While temps will be in the high 70s and low 80s each
day, the abundant sunshine will be met with sustained winds of
15-20 MPH and guest near 30 MPH. Current guidance keeps us just
below wind advisory criteria however should wind gusts increase
one may be necessary.

.LONG TERM...
(Sunday through Tuesday)
Issued at 333 AM CDT Wed Apr 24 2024

Breezy southerly winds will continue on Sunday as the ridge axis
continues to amplify and shift off to the east. In response to
this southwest flow, Gulf moisture will return to the area, as
seen by dewpoints rising back into the upper 50s to lower 60s.
However, without a lifting mechanism in place, the forecast will
simply remain very warm (and a little humid), but free of
precipitation as highs again will climb into the low to mid 80s.
This will begin to chance by Monday as an upper-low shifts from
the central Plains into the Great Lakes, pushing a cold front
toward the area. Still some uncertainties with the timing of this
front -- and with things trending a little later Monday may also
by a very warm and mostly dry day with highs in the 80s in spite
of increasing cloud cover. However, by Monday evening/night into
Tuesday, this front will likely push across the Tennessee Valley,
bringing at least medium chances (40-50%) for showers and
thunderstorms during this window.
